Threat Spotlight: Group 72

This post is co-authored by Joel Esler, Martin Lee and Craig Williams

Everyone has certain characteristics that can be recognised. This may be a way of walking, an accent, a turn of phrase or a style of dressing. If you know what to look for you can easily spot a friend or acquaintance in a crowd by knowing what characteristics to look for. Exactly the same is true for threat actors.

Each threat actor group may have certain characteristics that they display during their attack campaigns. These may be the types of malware that they use, a pattern in the naming conventions of their command and control servers, their choice of victims etc. Collecting attack data allows an observer to spot the characteristics that define each group and identify specific threat actors from the crowd of malicious activity on the internet.

Talos security and intelligence research group collects attack data from our various telemetry systems to analyse, identify and monitor threat actors through their different tactics, techniques, and procedures. Rather than give names to the different identified groups, we assign numbers to the threat actors. We frequently blog about significant attack campaigns that we discover, behind the scenes we integrate our intelligence data directly into our products. As part of our research we keep track of certain threat actor groups and their activities. In conjunction with a number of other security companies, we are taking action to highlight and disrupt the activities of the threat actors identified by us as Group 72. Read More »

Threading the Needle on Privacy and Malware Protection

We have been clear that we have a distinct approach to Advanced Malware Protection (AMP), specifically the unique way in which we leverage the compute and storage capabilities of the public cloud. Doing so enables us to do a great number of things to help customers more effectively fight malware, particularly when compared to traditional, point-in-time anti-malware systems of the past 20 years.

Top of Mind: Cybercrime–This Time It’s Personal

The axiom “Quality, not quantity” has been adopted by everyone from stock pickers to those trying to successfully navigate the online dating scene. Now cybercriminals are also putting this philosophy to practice.

The fundamental shift away from mass spam attacks to more targeted threats with potentially bigger payoffs is top of mind to me. This trend is detailed in a new report by Cisco’s Security Intelligence Operation (SIO).

Specifically on the issue of spam, Cisco’s research reveals that mass spam volumes dropped from 300 billion daily spam messages to 40 billion between June 2010 and June 2011. Although 40 billion is still a huge number, signifying that spam is still an issue, the trend that’s most alarming is the threefold increase in spearphishing and the fourfold increase in personalized scams and malicious attacks such as malware.

Cisco 2Q11 Global Threat Report

Data breaches dominated security news during the first half of 2011 and companies across all industry sectors were equally impacted. Many of these breaches resulted from advanced persistent threats; others resulted from SQL injection and other brute force intrusions. In all cases, customer data and corporate intellectual property were at risk.

In the Cisco 2Q11 Global Threat Report, Cisco CSIRT Manager Gavin Reid discusses the unique challenges of APTs and network intrusions. Gavin offers real world practical advice from a frontline perspective, offering valuable pointers for tweaking and using the tools you probably already have in place.

Cisco CSIRT on Advanced Persistent Threat

For corporations, Advanced Persistent Threat (APT) is a widely publicized yet little understood topic.  Does it exist?  Is it a real threat?  How can an organization tell if it is impacted?

The Cisco Computer Security Incident Response Team (CSIRT) is a global team of information security professionals responsible for the 24/7 monitoring, investigation and response to cyber security incidents for Cisco-owned businesses. CSIRT engages in proactive threat assessment, mitigation planning, incident detection and response, incident trending with analysis, and the development of security architecture. This article will provide the Cisco CSIRT team’s perspective on APT, and is the fifth in a series of blog posts on related issues from CSIRT’s point of view.  As with the other posts, provided here are some real-world examples and techniques that will hopefully help organizations utilize existing tools and processes, or even understand gaps in security infrastructure.  Read on to find out more.
